Air-cooled mine transformer

Abstract

The invention discloses an air-cooled mine transformer, which comprises a mounting plate, a protection box is fixed on one side of the mounting plate, both sides of the protection box are provided with limiting slots, and the opposite sides of the limiting slots are Slide grooves are provided on the side walls, a moving block is installed in the limiting groove, a cavity is arranged in the moving block, and two rotating rods are installed in the cavity, and the two sides of the rotating rod Rollers are all provided, and the rollers are located in the chute, a first gear is arranged on one of the rotating rods, a driving device is fixed at the bottom of the cavity, and a second gear is fixed at the end of the output shaft of the driving device, and The first gear and the second gear mesh with each other, and a support frame is fixed on the upper ends of the two moving blocks, and an arc-shaped slide groove is arranged on the support frame. The invention realizes the automatic heat dissipation treatment of the transformer through the combination of the driving device, the gear, the adjustment mechanism and the blower, not only improves the heat dissipation efficiency, but also facilitates adjustment and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an air-cooled mine transformer. Background technique [0002] Transformer specially used as mine power supply. Divided into mine-used general transformers and mine-used explosion-proof transformers, they are used in mines where there is coal dust and biogas but no explosion hazard, and are used for electric drive and lighting. This transformer is oil-immersed. Its internal structure and working principle are the same as those of ordinary oil-immersed power transformers. The main difference lies in the shell and the inlet and outlet devices. The general mine transformer has a solid structure and a low appearance. There is no oil storage tank on the upper part of the transformer, and there is a proper space on the oil surface in the oil tank to prevent excessive pressure in the oil tank when the vent hole on the tank cover is blocked. The mechanical strength of the oil tan...

Problems solved by technology

The high-voltage and low-voltage incoming and outgoing lines of mining transformers use cable junction boxes, and insulating glue is poured into the boxes. At present, during the use of mining transformers, a lot of heat is often generated. However, the current method can only rely on cooling holes to dissipate heat. , not only low efficiency, but also poor effect, very inconvenient, for this reason, we propose an air-cooled mining transformer to solve the above problems
